Abstract
In a pulse echo ultrasonic velocity measuring apparatus timing gate signals corresponding to the transit time of search signals traveling through a workpiece are generated. The quantity of fixed frequency pulses occurring during successive timing gate signals is counted and accumulated using time interval averaging techniques until a predetermined quantity of pulses commensurate with the thickness of the workpieces is accumulated. Concurrently, the quantity of search signals required to accumulate the predetermined quantity of pulses is counted. The quantity of search signals counted is commensurate with the acoustic velocity of the workpiece.
